tolng jwb brailny plisss buat bsk

8

V = 1/2 × π r2 t
= 1/2 × 3,14 × 10,5 × 10,5 × 24
= 1/2 × 8.308,44
= 4.154,22 dm3

8.V=1/2×π×r²×t
     = 1/2×22/7×10,5×10,5×24
     =4158 dm³
9.tidak ada ukuran
10.V= s×s×s                     V=π×r²×t
       =7×7×7                        = 22/7×1,75×1,75×10
       =343  dm³         +          =92,25 dm³                            = 439,25 dm³
maaf bila salah
